Mobile Centrifugal Fan (Explosion-Proof Type A)
Explosion-proof mobile centrifugal fan for grain aeration, silo ventilation, fumigation circulation and grain-drying systems.

Type C mobile centrifugal fan for grain aeration, silo ventilation, fumigation circulation and grain-drying systems.
The Type C mobile centrifugal fan provides flexible airflow for grain storage and drying applications. Airflow, pressure, motor configuration and accessories can be selected to match the operating requirements.
Mobile Centrifugal Fan (Type C) belongs to Yosinda’s grain ventilation fans range. Typical uses include Suitable for deep-grain aeration and moisture reduction in flat-storage warehouses, silo air exchange and fumigation circulation, shallow-grain ventilation, and air supply or exhaust for grain-drying towers. For grain aeration, the depth and condition of the stored grain affect resistance and operating duty. Drying, moisture reduction, silo air exchange and fumigation circulation require different selection inputs. Specify the storage layout and handled atmosphere, including any dust protection requirements.
